[
復數(shù)
ADT
的描述
]
ADT complex{
數(shù)據(jù)對象：
D={ c1,c2
c1,c2
∈
FloatSet }
數(shù)據(jù)關(guān)系：
R={ <c1,c2>
c1
c2
}
基本操作：創(chuàng)建一個復數(shù)
creat(a);
輸出一個復數(shù)
outputc(a);
求兩個復數(shù)相加之和
add(a,b);
求兩個復數(shù)相減之差
sub(a,b);
求兩個復數(shù)相乘之積
chengji(a,b);
等等
;
} ADT complex;
實現(xiàn)復數(shù)
ADT
可以使用面向過程的程序設(shè)計方法，也可以用面向?qū)ο蟪绦蛟O(shè)計方法。
